BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary seat mounted on a seat of an automobile, an airplane or the like, and more particularly, to a vehicle in which a footrest is removably attached to a tip portion of the auxiliary seat. It is related to the auxiliary seat.

2. Description of the Related Art A young person or a disabled person who cannot sit alone in a car seat, or a young infant who can sit in a car seat but cannot cope with shaking and vibration while the car is running are seated in a car seat. Allowing them is extremely dangerous.

For the purpose of preventing such a danger, it is common practice to mount an auxiliary vehicle seat having a structure suitable for restraining an infant on the seat of an automobile. These vehicle-mounted auxiliary seats are generally known by the names such as "child seats".

The above-mentioned known auxiliary seat is constituted by a combination of a base for fixing the auxiliary seat to the seat of the automobile and a seat main body for restraining an infant, and the seat main body is inclined on the base. It is common to have a reclining structure so that the angle can be changed freely.

Recently, the auxiliary seat is equipped with a footrest for mounting the infant's foot on the tip of the base so that the infant sitting on the auxiliary seat can place the foot thereon. It's coming.

[0006]

It is known that the auxiliary seat receives a considerable braking force when the vehicle is suddenly braked or in an emergency such as a collision, and the entire auxiliary seat moves to the front of the vehicle seat. ing.

When a footrest is used, it does not matter if the infant's foot is accurately placed on the upper surface of the footrest. However, the infant sometimes hangs his foot on the front surface of the footrest as shown in FIG. There is. When the auxiliary seat moves forward due to sudden braking or collision shock in such a state, as shown in the example of Fig. 10, the legs of the infant are placed between the tip of the footrest and the instrument panel of the car or the back of the front seat. There was a risk of being caught between them and causing an accident such as a bone fracture.

Further, when the usage method of placing the auxiliary seat on the automobile seat with the rear facing is carried out (placement in the direction facing the mother), in the above-described known structure, the protruding length of the footrest is long and the tip portion thereof is long. Has a drawback that it cannot be used with the footrest extended because it collides with the backrest of a car seat.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and seeks to address the problems.

That is, according to the present invention, the footrest is mounted on the base so that the footrest can be freely taken in and out. Moreover, the footrest has a locking projection protruding from the back surface thereof, which abuts against the locking projection formed on the base. In addition, when a collision or other impact is applied, the vehicle-mounted footrest is constructed so that the locking protrusions protruding from the back surface of the footrest can pass over the locking protrusions formed on the base and be stored inside the base instantly. It is intended to provide an auxiliary seat for

SUMMARY OF THE INVENTION According to the present invention, in a vehicle-mounted auxiliary seat in which an auxiliary seat main body is mounted on an upper surface of a base so as to be able to adjust an inclination angle, an infant's foot can be placed from the tip of the base. The main point of the invention is an in-vehicle auxiliary seat with a footrest in which the footrest is mounted so as to be retractable.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

In the auxiliary seat generally indicated by A, the auxiliary seat body 2 is reclinably attached to the upper surface of the base 1, and the belt locking recesses 11 are provided on both sides of the rear upper surface of the base 1 so as to face each other. , 11 is configured to fix the auxiliary seat A by inserting and locking the seat belt 3 originally installed in the automobile seat so as to pass through.

The structure for mounting the auxiliary seat main body 2 on the base 1 and its upper surface so that the tilt angle can be freely adjusted is known from the description of Japanese Utility Model Laid-Open No. 3-85249, particularly from the description of FIG. Therefore, detailed description of this is omitted.

Reference numeral 4 denotes a footrest that is attached to and removed from the base 1 so that the footrest can be freely retracted so that a length of about half of the entire length of the base 1 can be freely withdrawn.

The footrest 4 is made of a synthetic resin plate or the like having a thickness suitable for placing the foot of an infant, and the sliding distance (the length of insertion / removal of the footrest 4) near both sides of the rear part. ) For regulating the sliding control groove 41, 41
The guide protrusions 12 and 12 projecting upward from the base 1 are fitted in the sliding restriction grooves 41 and 41.

Reference numeral 42 designates a groove for sliding guide formed in the center of the back surface of the footrest 4 in a concave shape.
The slide guide groove 42 is formed in a concave shape at a position sandwiched by the 1 and 41, and both side portions of the slide guide groove 42 formed in the concave shape abut on both side edges of the two slide guides 13 and 13 projecting in the base 1. This ensures that the footrest 4 slides (retracts) in the front-rear direction accurately. (See Fig. 4)

Reference numeral 5 is a projection for maintaining a stop position which is provided downwardly near the rear end of the rear surface of the footrest 4, and is a projection 61 for retreat control which is provided near the front side of the base 1 when the footrest 4 is pulled out. When the footrest 4 is stowed in the base 1, the footrest 4 is restrained from being stowed (immersed) in the base 1 by abuttingly locking the front side surface.
The foot restraint 4 is restrained from being pulled out by contact with the rear side surface of the pullout restraint protrusion 62 projecting from the rearward position of the retract restraint protrusion 61, so that the footrest 4 is pulled out.

It should be noted that the retracting restriction projection 61 and the drawer restriction projection
The distance from 62 is matched with the sliding distance of the footrest 4 (distance for taking in and out).

Further, the height of the stop position maintaining projection 5 projecting on the back surface of the footrest 4 is set to a height which is slightly locked to the upper end portion of the retreat restricting projection 61 projecting on the base 1 side,
The height of the footrest 4 is set such that when a load of appropriate strength (load due to brake braking, shock at the time of collision, etc.) is applied to the tip end portion of the footrest 4, it is possible to instantaneously ride over the retreat restriction projection 61 and retreat. Further, the height of the withdrawal restricting projection 62 is also set to the same height so that the stop position maintaining projection 5 can easily get over the withdrawal restricting projection 62 when a force for manually pulling out the tip portion of the footrest 4 is applied. . Reference numeral 6 in the drawing denotes a pull-out gripping portion formed on the rear surface of the tip portion of the footrest 4.

[0021]

As described above, the present invention provides the footrest 4
Since the structure is such that it can be pulled out to the base 1,
As shown in the example, when the infant's foot hangs down to the front position of the footrest 4 pulled out to the front position of the base 1, even if the entire auxiliary seat A moves to the front side due to sudden braking, etc. The abutting footrest 4 is instantaneously retracted by the reaction force of the infant's foot as shown in FIG. 10 and stored in the base 1, so that various troubles caused by the conventional structure can be completely avoided. It can exhibit excellent characteristics.

Further, according to the present invention, the footrest 4 is constructed so that it can be pulled out so that it can be stored in the base 1. Therefore, as shown in the example of FIG. 11, the entire auxiliary seat A can be placed rearward to face the guardian who is the driver. Thus, there is an advantage that it can be used in such a manner that an effect which cannot be obtained by the conventional structure can be exhibited.
